TAIBULATOFL SPECIFICATION forming part of Letters Patent No. 777,286, dated December 13, 1904.

Application filed March 22, 1904. Serial No. 199,463. (No model.)

To all whom, t may concern:

Be it known that I, CARL AUGUST J onmssnN, a citizen of the United States, and a resident of Washington, in the District of Columbia, have invented certain new and useful Improvements in Tabulators for Type-Writing Machines, of which the following is a specification.

My invention relates to tabulators of that class in which stops are mounted in position to be moved into and out of the path of a part of the paper-carriage, so that said stops may be set to arrest the carriage at certain points. The preferred embodiment of this class of tabulators has the stops mounted upon a tabulating-frame which normally holds the stops out of position to engage the carriage, but which may be shifted into position to engage the carriage by means of the`so-called tabulater-key, and when so shifted or held into engagingv position the stops carried by said frame will successively arrest said carriage as the engaging projection reaches the successive stops. These arrangements have usually been further provided with means whereby the pressing of the tabulator-key will release the escapement, so that the carriage remains directly under the influence of its feed-spring until arrested by the first stop to be encountered, the tabulator-key being released and againpressed, if desired, as each stop comes into play to permit the carriage to move on to the next stop. ln this class of tabulators it has been the custom to set the stops in different positions corresponding to points at which it is desired to arrest the carriage uin writing tabulating-work. It frequently happens that an operator desires to use a writing'- machine for more than one form of tabulated work, and in such cases it becomes a matter of inconvenience to frequently shift some or all of the stops to adapt the machine for the different forms.

The object of my invention is to overcome the inconvenience referred to; and my invention consists in providing the tabulating portion of the type-writer with means whereby groups or series of stops may be set simultaneously by a movable member which controls their position. This movable member is preferably in the form of a bar having longi-` tudinal movement on or relatively to the tabulating-frame and having means for engaging the stops to move them or to determine their movements into and out of effective position on the tabulator frame. I These engaging' means on the controller-bar are so located or are so constructed that they may be located at will in such positions that on imparting one movement to the bar all of the stops desired for use in one particular form of tabular work will be moved into effective position, while all of the remaining stops move into ineifective position, and thereafter on imparting another movement to the bar another grouping oi the stops of the tabnlator will be set for doing tabular work on another form. The engaging means on the controller-bar may be so located that some of the stops will remain in effective position in all groupings of the stops-- as, for instance, when such stops are common to all of the forms for which the machine, is to be set. I shall illustrate my invention by means of a controller-bar which engages the stops to move them out of effective position and permits the stops to move into elfective position under the action of a springI or similar means combined with each stop; but obviously these conditions might be reversed, so that the stop is moved into effective position by engagement of the controller-bar and provided with means which causes it to assume ineffective position when disengaged by the controller-bar, or thecontroller-bar might be arranged to positively move the stops in both directions. Again, I have employed for purposes of illustration a controller-bar which causes but two groupings of the stops by its movements in opposite directions; but obviously this bar could be made to assume a number of positions intermediate of its two opposite limits of movement, each of which positions would cause a separate grouping of the stops, and this without departing from the spirit of my invention.

In order that the invention may be more fully understood, I will now proceed to describe the same with reference to the accompanying drawings, which show one embodiment of the invention by way o1' illustration.

In said drawings, Figure 1 is a rear view o1' the upper portion o1' a type-writer equipped with a tabulator of well-known construction and having my present improvement applied thereto. Figs. 2, 3, and 4 are plan views o1' the tabulator-frame, showing the scale-bar, the relation to the stops thereto, and the sliding controller-bar with its cams for engaging the stops to move them out of eiective position and to permit them to return to effective position when released, Fig. 1 showing the controller-bar disengaged from all the stops and Figs. 2 and 3 showing the controller-bar engaged with different stops to produce two separate groupings of stops. Figs. 5 and 6 are a plan and an edge view of the controllerbar. Fig. 7 is a detail view of one end of the controller-bar, in which the cams or engaging means are shiftable or adjustable on said bar, so as to vary its scope of usefulness and adapt it for any desired form of rtabular work. Fig. 8 is a vertical sectional view of a portion of the tabulating-frame, showing a stop mounted thereon, the scale-bar for indicating its position, and the controller-bar by which the stops are moved.

1 represents the tabulator-frame o1' a typewriter, having a bar 2, stops 3, mounted on said bar, and a scale 4, indicating the relative positions of the stops. The tabulator-frame is constructed with teeth 5, which receive tongues 6, Fig. 8, on the stops to fix said stops in positions to which they may be adjusted. In order to shift the stops, they may be swung outwardly on the rod 2 until their tongues 6 disengage from the teeth 5, after which the stops may be slid longitudinally on the rod 2 to any desired position and thereafter swung inwardly again to bring their tongues in er1- gagement with the teeth to hold the stops in position. 'Io hold the stops against swinging on the rod 2, spring-pressed balls 7 are litted in pockets in the stops and made to engage in the longitudinal groove 8 in the rod 2. These balls, however, yield when the stops are swung outwardly-as, for instance, by downward pressure on the knob Q-and to hold them in their outer position until they are properly adjusted bar 2 is provided with an additional groove 10, which receives the balls when the stops are in their outward position. Each stop is provided with a projection 11, through which it engages the carriage when the tabulator-frame is swung inwardly toward the carriage. Then a stop is swung outwardly on the frame, projection 11 does not enter the path of the carriage, and such a stop is therefore inoperative or is ineffective or is in ineifective position.

As thus far described the parts are known in the prior art of tabulators for writing-machines. In carrying out my present invention according to the embodiment adopted for illustration I provide means for moving the stop 3 outwardly in opposition to its retaining-ball 7, so as to render such stop ineffective and for disengaging the stop, so as to permit it to return to normal position when it is desired that the stop shall be effective, this outward movement o1' the stop, however, not being sufcient to permit the ball 7 to pass into the outer groove 10, so that said ball will tend to return the stop and not hold it in its outer position. To impart movement to the stops, I employ a controller bar 12, which is conveniently mounted beneath scale 4 and secured in position by the screws 13, which hold said scale, the controller-bar being held by longitudinal slots 14, so that it may move longitudinally beneath the scale. The controller-bar 1Q carries cams 15, which when the bar is moved longitudinally will engage the indeX-ngers 16 on the stops and impart a sufficient movement to said stops to carry their engaging projections 11 out of effective position. The cams 15 are so located that when the bar is moved to one limit of its motion one group o1' stops will be engaged and moved out of eiifective position, while the remaining stops form a grouping in effective position to arrest the carriage successively at dierent points corresponding to a ruled form to be written on. Then the controller-bar is moved to the other limit o1' its motion, the engaged stops will be released and permitted to return to effective position, while the remaining stops or some of them will bel moved out of eective position and a new grouping o1' stops corresponding to a different form to be written will have been established. It may happen that some stops are common to both forms for which the .machine is adjusted, in which event the displacingcam on the controllerbar corresponding to such a stop will be omitted and such stop will be in effective position at all times. As shown in Fig. 2, the controllerbar may be stopped at an intermediate position, in which none of the stops will be engaged and all will remain efective, thus giving a third grouping of the stops. Obviously this third grouping could be modied so that some of the stops could be thrown out. In fact, the invention is susceptible of a wide range of application in forming different groupings of stops, the range of longitudinal movement of the controller-bar being correspondingly provided for. The controller-bar 12 may have the cams formed integral with it, as shown in Fig. 5, in which case a special bar would be made for any particular set of forms for which it is desired to adapt the machine. The controller-bar being extremely simple and cheap in construction and being easily replaced could readily be made for any special purpose, or the controller-bar may be constructed as suggested in Fig. 7, in which each cam 15a is inserted in the seat 15b, formed IOO IIO

in the controller-bar and there secured by a screw 15C. This arrangement provides for setting the cams in such positions as to obtain any desired groupings of the stops, range of' which is very Wide in view of the longitudinal adjustability of the stops themselves on the rod 2.

I-Iaving thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

l. In a tabulator, the combination oi a frame or support, al stop thereon movable into and out of effective position and a controllerbar sliding parallel to the frame or support and controlling the position of' the stop.

2. In a tabulator for type-Writers, in combination with the paper-carriage and tabulatorframe; stops carried by one of said parts and movable into and out of' effective position, means for bringing the stops on one of said parts into engagement with the other of' said parts to arrest the paper-carriage, and means slidingparallel to the part which supports the stops, adapted to engage the stops and move them into and out of' effective position.

3. In a tabulator for typewriters, the combination of' a series of stops having means for yieldingly holding them in effective position and a longitudinally-movable bar engaging said stops to move them out of such position.

4. In a tabulator f'or type-Writers, the combination of the tabulator-frame, stops carried thereby and independently movable thereon to and from effective position, and a controller-bar mounted on said tabulator-frame controlling the positions of said stops.

5. In a tabulator for typewriters, the coinbination of a tabulatorf1ame, stops carried thereby and independentlymovable thereon to and from effective position, a controllerbar reciprocating on said tabulatonframe and cams carried by said controller-bar adapted. to engage the stops for controlling their positions.

6. In a tabulator f'or type-Writers, the combination of' a tabnlator-f'rame, stops carried thereby and independently movable into and out of effective position thereon, a controllerbar mounted to reciprocate on said frame, and cams carried by said controller-bar engaging the stops to control their positions; said cams being positioned on the bar to engage some ofI the stops when the bar is in one position and to engage others of the stops when the bar is in another position.

7. In a tabulator f'or type-writers, the combination of the stops, the controller-bar reciprocating relatively to the stops, and the cams on the controller-bar engaging' the stops to control their positions; said cams being adjustable for the purpose set f'orth.
